1. Good call on the Mayor. I'll make the change effective immediately.
2. I will consider this suggestion. I felt that Student should be able to win without picking a mentor because they can be killed and have no vests, but you make a fair argument.
Q: How does the Jailer work?
A: The jailer 'jails' his/her target at night, opening a night chat that night with them that night only. In this Night Chat, they may interrogate their target, and if they don't trust their target, then they can choose to Execute them. The Jailer's target is basically took away during that night, preventing them from using their night action and making any night actions that would be used on them fail. The Jailer can't execute on night 1 or during a day where there was a successful lynch, however, I might buff it to allow an Execution even if there was a lynch.
Q: Can the Witch control the Godfather?
